Summary
SQL injection vulnerability in the order_by parameter of the /customers/search endpoint in Alex Tselegidis EasyAppointments <= 1.5.1. Unsanitized user input passed to the CodeIgniter Query Builder's order_by method allows time-based queries and schema enumeration. Under certain MySQL configurations, it may lead to remote code execution via writing a PHP shell using INTO OUTFILE.
Risk Assessment
This can allow attackers to extract database data and, under favorable conditions, achieve remote code execution on the server.
Recommendation
Upgrade EasyAppointments to a version above 1.5.1 and use parameterized SQL queries instead of direct input concatenation.

- CVE-2026-100109Critical
The Security For WooCommerce WordPress plugin from 1.0.10 to 1.0.16 does not perform capability checks when creating users through an action available to unauthenticated visitors, and lets the caller choose the new account's role. This allows unauthenticated attackers to create administrator accounts and take over the site.
- CVE-2026-123025Critical
An OS command injection vulnerability was discovered in the Google Cloud DNS validation module of the OPNsense os-acme-client plugin through 4.17. The DnsGcloud::prepare() method decodes the dns_gcloud_key model field and directly interpolates the gcloud_account and gcloud_project string fields into a shell command passed to proc_open() via LeUtils::run_shell_command() without validation or escaping. A remote authenticated user with privileges to issue or renew certificates through the WebGUI/API can achieve arbitrary code execution as root.

In G4KLX DStarGateway and F4FXL DStarGateway before 7b75de6, dstarCallsignToAPRS in APRSUtils.cpp has an integer underflow via an empty RS-MS1A sender field.
- CVE-2026-122321Critical
Kyverno 1.18.0 before 1.19.2 contains a signature verification bypass in verifyImages because cached verification results are keyed by the image reference string (such as a tag) rather than bound to the verified digest, so cache hits skip signature and attestation checks. An attacker who can submit workloads and move a registry tag can warm the cache with a signed image, repoint the tag, and have Kyverno admit the workload and use mutateDigest to pin the unverified digest.
- CVE-2026-122313Critical
Kyverno from 1.17.0 before 1.19.2 contains a privilege escalation vulnerability that allows namespace-scoped tenants to modify resources in other namespaces through NamespacedMutatingPolicy targetMatchConstraints.expression CEL output lacking namespace checks. Attackers can emit a literal target such as another tenant's RoleBinding, which the cluster-wide background controller then mutates to add attacker subjects or alter Roles, NetworkPolicies, and ConfigMaps.
- CVE-2026-122311Critical
Kyverno from 1.16.0 before 1.19.2 fails to validate path segments in the resource argument of resource.get() and resource.post(), allowing namespaced CEL policies to escape their namespace. Tenants who can create a NamespacedValidatingPolicy can insert .. segments to read and write arbitrary cluster objects using the admission controller's ServiceAccount, leading to cluster takeover.
- CVE-2026-122310Critical
Kyverno from 1.19.1 before 1.19.2 validates a Policy's context.apiCall urlPath after cleaning it but executes the raw path, whose fragment or query the Kubernetes client discards. A namespace-scoped user who can create a Policy can hide ../ segments behind # or ? to reach cluster-scoped endpoints with Kyverno's ServiceAccount, gaining cluster admin.
- CVE-2026-122304Critical
Kyverno from 1.17.0 before 1.19.2 contains an authorization bypass vulnerability that allows namespace admins to escape namespace confinement because the cleanup controller builds its context loader with a nil policy. Attackers can create a namespaced CleanupPolicy with apiCall or globalReference context entries to read cross-namespace Secrets and modify validatingwebhookconfigurations using the cleanup controller's ServiceAccount.
- CVE-2026-122303Critical
Kyverno from 1.17.0 before 1.19.2 contains an authorization bypass vulnerability that allows namespace tenants to overwrite resources in other namespaces via NamespacedMutatingPolicy mutate-existing targetMatchConstraints.expression. Attackers can return a CEL map literal fabricating a target with an attacker-chosen metadata.namespace, causing the privileged background controller to overwrite Secrets, Deployments, or policies cluster-wide.
- CVE-2026-122302Critical
Kyverno before 1.19.2 contains a privilege escalation vulnerability that allows namespace admins to create resources beyond their RBAC because generate-rule admission checks verify the controller's permissions, not the author's. Attackers can create a namespaced Policy with generate rules targeting other namespaces or cluster-scoped kinds, making the background controller create or clone resources cluster-wide.
Original NVD description (English source)
SQL injection vulnerability exists in the order_by parameter of the /customers/search endpoint in Alex Tselegidis EasyAppointments <= 1.5.1. The vulnerability arises from unsanitized user input passed to the order_by method of the CodeIgniter Query Builder, enabling attackers to perform time-based queries and schema enumeration. Under certain MySQL configurations, the flaw may lead to remote code execution by writing a PHP shell using INTO OUTFILE.
